Tang Ziren is a doctor with the emergency department of a hospital in Beijing. Lately when having a vocation at Sea World of San Diego, he happened to see an American tourist who had a cardiac arrest. With the approval from the family of the tourist, Tang performed CPR on her for about 10 minutes and asked other people to call 911.

"It is my job to save life, I did not think too much," said Tang. The tourist eventually could breathe by herself with Tang and EMTs' help. To thank Doctor Tang, San Diego Sea World provided him with a free buffet where he can enjoy the performance of Shamu (Shamu is the star killer whale in the park) alone.
